KLIF-FM broadcasts in HD Radio. The main radio signal and HD-1 signal air the top 40 format. KLIF-FM had an HD2 signal initially started as a Dance format as "Energy 93.3 HD2". In 2009, it has switched to a simulcast of its AM News/Talk sister station KLIF 570 AM. As of February 2013, the simulcast has been relocated to KSCS 96.3 HD2, and KLIF-FM's HD2 signal is currently dark.

The KLIF calls have a long history of being associated with CHR/Top 40 music. The original KLIF at 1190 on the dial was Dallas/Fort Worth's most popular Top 40 music station from the 1950s through the 1970s.

KLIF-FM temporarily stopped transmitting its digital signals ("HD Radio") in late November 2011 and resumed in early January 2012. The HD signal ceased again sometime in the summer of 2014.

Marcos A. Rodriguez was the first to control the license after having successfully obtained it directly from the Federal Communications Commission (FCC). After his financing source defaulted, Rodriguez sold the license to Susquehanna Radio. Cumulus Media subsequently took control of the station in May 2006 as part of its acquisition of Susquehanna, instituted cost-cutting measures, and completely restored a classic rock format after the station had experimented with more recent rock offerings.

93.3 FM began broadcasting on October 31, 1996 as KNBR-FM "The Zone", with an adult alternative format. The call letters KNBR-FM were only short-term, as they were changed to KKZN to match the moniker on December 20, 1996. After a stunt with episodes of "The Bob Newhart Show", the station became KKMR "Merge" on August 31, 1999. The switch to KDBN "The Bone", with a classic rock format, occurred on January 3, 2002. This produced an initial spike in ratings, though the station lost much of that audience, as the years progressed. The KKZN callsign is currently in use on a Denver, Colorado, AM radio station.

On Friday, April 24, 2009, KDBN-FM changed its format with a weekend stunt, broadcasting only music by the Dave Matthews Band with limited commercial interruptions. The station completed the format switch back to Adult Album Alternative "FM 93.3 - Quality Rock" on Monday, April 27, 2009. On-air staff included The Regular Guys, a morning show syndicated from Atlanta, Alexis (middays) and Scott Gaines (afternoons).

The station was formerly an affiliate of the Dallas CowboysRadio Network.[1] The old KDBN calls, as an abbreviation for Dallas Business News, were once used at 1480 AM in Dallas for a business news format from September 21, 1989 to September 4, 1991.

On September 2, 2009, the station began stunting again, urging listeners to tune in that Friday (September 4) at Noon.[2] At that time, the station launched a top 40 format as "i93", and on September 7, a callsign change to KLIF-FM was made.[3] As a reference to the station's I branding used for newer Cumulus-launched top 40 stations, the station's new top 40 format launched with The Black Eyed Peas' I Gotta Feeling. The station aimed for an older audience; rival 106.1 KISS-FM skewed toward younger listeners.

KLIF was the flagship station for Nights Live with Adam Bomb. Since the format change later on, it has moved to Houston with KRBE-FM.

In September 2014, websites were registered showing a possible rebranding or format change to rhythmic Top 40/CHR, urban, classic hits, oldies, smooth jazz, or rhythmic oldies. The registrations follows the recent hiring of former KBFF program director Louie Cruz for the same position at KLIF-FM. This station has not been able to make up ground on KHKS as it continues to hover right below a 2 share in the Dallas/Fort Worth Nielsen ratings of August 2014.[4] The change was confirmed on October 3 of that year, when 93.3 began running liners promoting that "Something New Arrives At 93.3" at 5 PM that day. While the station still maintained its Top 40 format as before, KLIF-FM began leaning towards rhythmic CHR.

On November 14, 2014, KLIF-FM began playing Classic hip hop songs during the holiday season, only to be upstaged an hour later by KSOC, who dropped their Urban AC direction to go full time with Classic Hip-Hop as "Boom 94.5." It is not known if this was done intentionally, or if KLIF-FM was trying to pull a pre-empted strike to bring the format first to the area before another station picked it up. The flip has also resulted in Mediabase changing KLIF's reporting status from Top 40/CHR to Rhythmic.[5]

On December 2, 2014, at 6 PM, KLIF-FM shifted their format to urban contemporary, retaining the "Hot 93.3" branding, even though Mediabase continues to list the station as a Rhythmic reporter.[6] Competitors in the format include KKDA-FM and KBFB.
